Stuck Cross-Shafts

Sounds like you are close to a solution.  I initially tried hammering them out.  Then drilling them out - but I could never keep the drill straight.  So the acid was the best option discovered so far.  If you have a way to boost temperature that could be a help.

As far as disposal, lets just say that there is a spot in my gravel driveway where the weeds won't be growing for some time.

Some of them I could hammer out, but not this one…. I put it in the 20 ton press and pushed on it until it started to flex into an S shape.  I even tried a sledgehammer.  Acid is the only option for this one. 

I read that the acid can be neutralized with baking soda, so that’s what I did…Even though I’m not sure the weeds will grow in my driveway either…
